1. A wearable thermometer patch, comprising:

  • a substrate;

    a temperature probe unit mounted in the substrate and configured to measure temperature of a user'"'"'s skin, wherein the temperature probe unit comprises;

    a thermally conductive cup having a bottom portion mounted in an opening of the substrate;

    a force sensor configured to measure contact force between the temperature probe unit and the user'"'"'s skin;

    a plate;

    a first temperature sensor attached to a lower surface of the plate; and

    a second temperature sensor attached to an upper surface of the plate;

    a thermally-conductive adhesive attached to the temperature probe unit and configured to conduct heat between the temperature probe unit and the user'"'"'s skin, wherein the thermally-conductive adhesive affixes the first temperature sensor, the second temperature sensor, and the plate to an inner surface of the thermally conductive cup; and

    an adhesive layer under the substrate, the adhesive layer configured to attach to human skin.
